Example 2

A tank fixing device is used for fixing a tank 300 and controlling the tank 300 to rotate when the surface of the tank 300 is polished, and polishing each position of the tank 300, and the specific structure and the working principle of the tank are described in detail below.

As shown in fig. 7 to 10, the can fixing apparatus mainly includes a turntable 210, a base 220, and a can 300. Wherein, a gear ring 214 is fixedly arranged on the lower end surface of the turntable 210, a rotating support 215 is fixedly arranged on the lower end surface of the gear ring 214, and the rotating support 215 is rotatably arranged on the base 220. Specifically, the base 220 is fixed on the ground, a cylindrical protruding shaft is arranged at the center of the upper end face of the base, the rotating support 215 is of a cross-shaped support structure, a through hole or a groove matched with the cylindrical protruding shaft is arranged at the cross-shaped hinged position of the rotating support 215, and the rotating support 215 is sleeved on the base 220. A rotating rack 216 is arranged on the inner side wall of the gear ring 214 along the circumferential direction, a rotating motor 217 and a speed reducer 218 which are in transmission connection are arranged on one side of the cross-shaped support of the rotating support 215, and a gear which is meshed with the rotating rack 216 is arranged on an output shaft of the speed reducer 218.

After the can body 300 is fixed on the turntable 210, the rotating motor 217 is started to drive the gear on the speed reducer 218 to rotate, and the rotating support 215 is controlled to rotate along the center of the base 220, so that the turntable 220 and the can body 300 on the turntable 220 are driven to rotate. It should be mentioned that the lower end of the rotating support 215 is provided with the wear-resistant block 219, specifically, the wear-resistant block 219 is respectively installed on the lower end faces of the end portions of the four sides of the cross-shaped bracket, so that the lower end of the rotating support 215 can be prevented from being damaged due to direct contact friction with the ground when the turntable 210 rotates, and the service life of the rotating support 215 is prolonged.

However, when the can body 300 is directly placed on the turntable 210, the can body 300 is easily generated during the rotation of the turntable 210, which affects the grinding accuracy of the surface of the can body 300, and thus the can body 300 needs to be fixed. However, when the tank 300 is large or even huge, the tank 300 is very troublesome to fix, and in the prior art, the large tank is generally placed directly by its own weight, and no fixing measures are taken, so that the stability of the tank in rotation is poor. If corresponding equipment is adopted to fix the large tank body, the equipment usually needs extremely large weighing capacity, the structure is usually complex, the manufacturing cost is extremely high, the operation is complex, and the maintenance and replacement cost is also high. In view of this, the present embodiment takes the following measures.
